The HI 3826 ammonia portable test kit determines the ammonia concentration in water in several easy steps. The ammonia level in mg/L (or ppm), ammonia as nitrogen is determined by a colorimetric method. The Nessler reagent reacts with ammonia, under strong alkaline conditions, to form a yellow coloured complex. An addition of Reagent 1 for sea water ingibits precipitation of calcium and magnesium ions due to the presence of the alkaline Nessler reagent. The colour intensity of the solution determines the ammonia concentration: 2K2Hgl4 +2NH3 ? NH2Hg2I3 + NH4I + 4KI
